Tetraarylanthracenes containing several fluoro groups were synthesized using the ruthenium-catalyzed C–O or C–F arylation with arylboronates and their structural and spectroscopic studies were conducted. The RuH2(CO)(PPh3)3-catalyzed C–O arylation of aromatic ketones was found to be effective for the introduction of aryl groups containing multiple fluoro groups. Anthracenes possessing fluorinated aryl
使用钌催化的 C-O 或 C-F 芳基化与芳基硼酸酯合成了含有几个氟基团的四芳基蒽,并进行了它们的结构和光谱研究。发现 RuH2(CO)(PPh3)3 催化的芳族酮的 C-O 芳基化可有效引入含有多个氟基团的芳基。具有氟化芳基的蒽由 1,4,5,8-四甲氧基蒽醌通过 C-O 芳基化和羰基的还原分两步制备。还使用八氟蒽醌的 C-F 苯基化制备了含有氟化蒽部分的四苯基蒽。单晶X射线衍射分析表明,四芳基蒽上氟基团的位置导致晶体堆积结构的显着差异。
